Description

Technical Field

[0001] The utility model relates to the technical field of jaw crusher accessories, in particular to a jaw crusher tooth plate structure. Background Art

[0002] The jaw crusher consists of two tooth plates, a movable jaw and a static jaw, which form a crushing chamber and simulate the movement of the two jaws of an animal to complete the material crushing operation. There are strip jaw teeth on the tooth plates. The tooth plates are consumables. The jaw teeth are prone to cracking during long-term use, which reduces the working efficiency of this part of the jaw teeth and cannot reach a good working condition. Currently, the tooth plates on the market are all integrally formed. If some jaw teeth are damaged, the entire tooth plate needs to be replaced, which is a waste.

[0003] In the prior art, an authorized patent with announcement number CN212943085U discloses a jaw crusher tooth plate, including a jaw plate and jaw teeth detachably connected to the jaw plate, a plurality of long clamping grooves are provided on the jaw plate, the plurality of long clamping grooves are arranged in parallel and at intervals, the jaw teeth are clamped in the long clamping grooves, the jaw teeth include a wear-resistant section, a clamping section 1 and a clamping section 2 connected to the wear-resistant section, the clamping section 1 is clamped with the long clamping groove, the clamping section 2 is provided with an embedding groove, a clamping strip is clamped on the clamping section 2 between adjacent jaw teeth, and the clamping strip is clamped with the embedding groove.

[0004] When the above technical solution is in use, although it is connected to the jaw plate through the jaw teeth, since the jaw teeth are detachably connected to the jaw plate, when a single jaw tooth is damaged, only the jaw tooth can be replaced, thereby extending the service life of the entire tooth plate. However, there are still the following shortcomings: when the above device replaces the jaw teeth, the jaw plate needs to be removed from the jaw crusher before the jaw teeth can be replaced, so that the jaw plate needs to be disassembled and assembled back and forth during the replacement process, resulting in inconvenience in replacing the jaw teeth. In this regard, we propose a jaw crusher tooth plate structure to solve the above-mentioned problems. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. When the utility model is in use, when the jaw teeth need to be replaced, it is only necessary to remove the locking rod first, and after the locking rod is removed, the jaw teeth are translated toward the opening direction of the first groove, so that multiple L-shaped plug-in blocks are separated from the corresponding fixed blocks at the same time, and then the jaw teeth are removed. When installing new jaw teeth, the above steps can be reversed, so that the jaw teeth can be quickly replaced without disassembling and assembling the jaw plate back and forth, which greatly improves the convenience of replacing the jaw teeth after damage, and the overall structure is relatively simple, and the manufacturing cost is low;

[0014] 2. The plug-in cooperation of the multiple L-shaped plug-in blocks and the multiple fixed blocks provided in the utility model can strengthen the firmness of the connection between the jaw teeth and the jaw plate.
